Claims priority, application Great Britain February 16, 1956 4 Claims. (Cl. 131198) The present invention relates to tobacco pipes, cigarette holders and the like and has for its object to provide an improved tobacco pipe, cigarette holder or the like which whilst affording the smoker the same satisfaction as existing tobacco pipes, cigarette holders and the like, is more economical in its use of tobacco than the latter.

With this object in view the present invention consists in a tobacco pipe, cigarette holder or the like comprising a stem, said stem having a bore extending axially thereof, an opening in said stem substantially normal to and communicating with said bore, a first resilient arcuate element mounted coaxially on said stem in the region of said opening and firmly gripping said stem resiliently, a hole in said element coincident with said opening, and a second resilient arcuate element mounted coaxially on said first resilient arcuate element and rotatable with respect thereto, a slit in said second resilient arcuate element inclined with respect to the axis thereof and co-operating with said hole in said first resilient arcuate element whereby the efiective size of said hole may be varied by rotation of said second resilient arcuate element with respect to said first resilient arcuate element to vary the supply of air to said bore.

In order that the present invention may be more clearly understood and readily carried into effect reference will now be had to the accompanying drawings illustrating the same, and in which:

Fig. 1 is an elevational view of a tobacco pipe according to the present invention,

Fig. 2 is a part longitudinal sectional view of the pipe shown in Fig. 1.

Fig. 3 is a part longitudinal sectional view of a slightly modified form of tobacco pipe according to the present invention, and

Figs. 4 and 5 are perspective views of the arcuate elements used in the tobacco pipes shown in Figs. 2 and 3 respectively.

Referring first to Figs. 1 and 2 of the accompanying drawings, the stem 1 of the pipe is provided with an opening or hole 2 just in front of the bowl 3. The hole 2 extends to the bore 4 of the stem 1 and a resilient arcuate element 5 is mounted coaxially on the stem 1 and has a hole 6 which is positioned to coincide with the outer end of the hole 2. On account of its resiliency, the element 5 grips the stem 1 firmly. The opposite ends of the element 5 are flanged radially outwardly or upwardly as shown at 7 and 8 to provide a guideway for a second resilient arcuate element 9 mounted coaxially upon the resilient arcuate element 5 and having formed therein a slit or slot 10 inclined with respect to the axis of the element 9 and adapted for co-operation with the holes 6 and 2 in such wise that upon rotating the resilient arcuate element 9 upon the resilient arcuate element 5 about their common axis the eflective size of the holes 6 and 2 may be varied, thereby varying the amount of air admitted to the bore 4 and consequently to the smoke stream of the pipe. In assembling the resilient arcuate element 2,924,224 Patented Feb. 9, 1960 5 on thefstem 1, the ends of the element 5 are pulled apart to, a sufiicient extent to receive the stem 1 and thereafter the ends are released whereupon they tend to resume their original position and in so doing grip the stem 1 firmly as stated above. The resilient arcuate element 9 is assembled on the resilient arcuate element 5 by a similar procedure. However the assembled arrangeme'nt is such that the grip of the element 5 on the stem 1 dueto its resilience is firmer than the grip of the element 9 o'n the element 5 so that the element 9 can be rotated on the element 5 without disturbing the grip of the element 5 on the stem 1.

In the'modified 'form of the invention shown in Fig. 3, 11 is a resilient arcuate element which is provided with a plug 12 of any suitable material, e.g. metal or synthetic resin and 13 is a hole which'extends axially through the plug 12 and through the element 11. The plug 12 is fitted snugly into a hole 14 of appropriate size in the stem 1 and serves to anchor the element 11 against axial or rotary movement relatively to the stem. 1. As shown the opposite ends of element 11 are flanged radially outwardly or upwardly as shown at 15 and 16 to provide a guideway for a second resilient arcuate element 17 mounted coaxially upon the element 11. In assembling the element 11 on the stem 1 the ends of the element are pulled apart to a sufficient extent to enable the stem 1 to be recessed between them care being taken to locate the plug 12 in the hole 14. Thereafter the ends of the element 11 are released and tend to resume their original position: in so doing they grip the stem firmly. The resilient arcuate element 17 which is provided with a slit or slot 18 inclined with respect to the axis of element 17 is then assembled on the resilient arcuate element 11 in a manner similar to that just described in connection with the element 9 of Figs. 1 and 2.

Fig. 4 shows in detail the pairs of resilient arcuate elements 5 and 9 which are shown in Figs. 1 and 2 and Fig. 5 shows in detail the pairs of resilient arcuate elements 11 and 17 shown in Fig. 3.

In the case of a tobacco pipe I have found that best results are obtained when the hole 2 or 14 in the stem 1 is located immediately behind the bowl 3 and is preferably in the region of three-sixtyfourths of an inch in diameter, the slot 10 or 18 in the resilient arcuate element 9 or 11 being one-sixteenth of an inch wide and threeeighths of an inch in length. If a plug 12 is employed it may' be of cylindrical form and of one-eighth of an inch in diameter.

I claim:-

1. A smokers appliance comprising a stem, said stem having a bore extending axially thereof and an opening 7 therein substantially normal to and communicating with said bore, a first resilient arcuate element mounted coaxially on said stem in" the region of said opening and gripping said stem resiliently, said element having a hole therein coincident with said opening, and a second resilient arcuate element mounted coaxially on said first resilient arcuate element and rotatable with respect thereto, said second resilient arcuate element having a slit therein inclined with respect to the axis thereof and cooperating with said hole in said first resilient arcuate element, whereby the effective size of said hole may be varied by rotation of said second resilient arcuate element with respect to said first resilient arcuate element to vary the supply of air to said bore.

2. A smokers appliance as claimed in claim 1 in which said first resilient arcuate element has radially extending flanges at the opposite ends thereof to prevent axial movement of said second resilient arcuate element with respect to said first resilient arcuate element.
